The joke in the headline was made because dice are most commenly associated with gambling or board games (which often is gambling without the thrill of money being involved). Dice Jockey has timed and puzzle modes, but the general idea is that by rotating die, you line up dice of the same number, creating chains to either solve the puzzle or keep the game going a little while longer. The trailer will give you a better idea.
This looks a little confusing as you seem to have to be familiar with where the numbers on a die are situated in relation to each other, but after a few levels and rolling the dice back and forth, you'd probably get a good grasp on the concept. The game is out in the App Store today for $0.99. It might be brain wracking, but at least when you get a puzzle wrong, you can shout out, "oh craps!"
